CORPORATION OF NEW -DISINFECTING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 729,459, dated May 26,1903.

Application filed November 10, 1900. Serial No- 36,078. (No modelJ Toall whom it may concern.-

Be it known that I, CHARLES J. WALZ, a citizen of the United States, anda resident of the borough of Manhattan, in the city and State of NewYork, have invented a new and useful Improvement in Disinfect-in gApparatus, of which the following is a specification.

' My invention relates to an improvement in disinfecting apparatus,withthe object in view of providing a cut-oft for the liquid-discharge tubeof the reservoir or tank,whereby the said tube may be closed when it isdesired to pour more liquid into the reservoir or tank.

A further object is to provide an automatic cut-oft for the saiddischarge-tube whereby the tube is automatically closed when thefilling-cap of the tank is "removed and which will be opened as thefilling-cap is inserted into its position to close. the top of the tank.

A practical embodiment of my invention is represented in theaccompanying drawings, in which a Figure 1 represents a vertical centralsec- ,tion through the reservoir or tank, showing View showing theposition of the parts when the filling-cap is insertedinto its positionin the top of the tank. Fig. 3 is a top-plan view of the tank with thefilling-cap removed, and Fig. 4c is a transversesection taken in theplane of the line 4 4 of Fig. 1.

I have shown in the accompanying drawings only so muchof-thedisinfecting apparatus as will give a clear understanding of theconstruction and operation of the cut-0d.

The reservoir or tank for the. disinfecting liquid is denoted by A, andit may be made of any desired shape and size, that shown in theaccompanying drawings being of oblong cylindrical form. The top a of thetank is provided with a removable filling-cap B,

which has a screw-threaded engagement with the said top.

The bottomot the tank or reservoir A is denoted bye, and a shortliquid-discharge tubeG passes therethrough, the top and bottom of thesaid tube being a short distance above and below the bottom a of thesaid tank.

The means which I employ for cutting oif the flow of liquid through thedischarge-tube 0, when so desired,is as follows: A springactuatedcut-offvalve D is hinged at (Z upon a suitable support a uprising from thebottom 0!, of the tank. One arm of the said valve D is arranged inposition to open and close the top of the tube 0. The valve D is springactuated, so that it normally closes the discharge-tube C, theparticular device shown in the accompanying drawings being a coil-springE, which is interposed between the bottom of the tank and the oppositearm of the valve from that which opens and closes the saiddischarge-tube 0. The valve D is under the control of the filling-cap B,by means of a vertically-disposed operating bar or rod F, the lower endofwhich rests in engagement with the valve D and the other end of whichis held in position to be engaged and'depressed by the filling-cap B asthe cap is screwed into its position to close the tank. Upper and lowerguide-brackets ff serve to loosely retain the rod F in its position. Thestrength of the spring E is suflicient to raise the rod F and close thevalve D when the pressure is removed from the top of the rod F by theunscrewing and removal of the filling-cap B.

The tank A may be provided with the usual air-tube G, which extendsupwardly from the bottom a. to a point in proximity to the top a of thetank. 7

From the above description it will be seen that disinfecting'liquid maybe poured into the tank at any time, whether the tank be emptied or not,as the moment the filling-cap B is removed the discharge-tube is closed.This is a Very important point, and it will fur thermore be seen thatthe person who fills the tank must necessarily open the valve as hescrews the filling-cap into its position to close the top of the tank.l.

Itis evident that other forms of cut-off than that shown herein might beemployed without departing from. the spirit and scope of my invention.Hence I donot wish to limit myself strictly to the structure hereinshown and described; but

What I claim is- Disinfecting apparatus comprising a tank or reservoir,an air-tube opening through the bottom of the reservoir and extendingupwardly within the reservior to a point above the level which theliquid is intended to ooeupy within the reservoir, a discharge-tubeextending through the bottom of the reservoir with its lower end belowthe bottom of the reservoir and its upper end within the reservoir abovethe bottom of the reservoir, a valve mounted to rock toward and awayfrom the upper end of the tube within the reservoir, a spring havingatendency to hold the valve closed, a valve-operating rod arranged toworkthe valve in a direction opposed to the tension of the spring, the saidWitnesses:
